Device Security for Tech+

Securing devices involves multiple best practices: - Strong Passwords: Complex, hard-to-guess. 12+ characters, mix of letters/numbers/symbols. Unique per account. Change default passwords immediately. - Multi-Factor Authentication (MFA): Second factor (phone code, fingerprint) in addition to password. Greatly increases security. - Software Updates (Patching): Keep OS, antivirus, all software up-to-date. Updates fix security vulnerabilities. - Anti-Malware Protection: Install reputable antivirus. Keep definitions updated. Use built-in protections. - Firewalls: Filter network traffic. Ensure host-based firewall is on.

Common mistakes to avoid

Jumping into advanced certification depth instead of staying at Tech+ recognition level.

Choosing a related term without checking the exact device, service, or user need in the scenario.

Memorizing isolated definitions without connecting them to simple workplace examples.
